No. seaeia Be it known that I, FREDERICK M. SfmvuN s, a citizen of theUnited States, residing 'at Waterbuiy,in the `county of New Haven andState of Connecticut, have invented cer.

tain new and useful Improvements in Soap- Dispensers, of which thefollowing is a full,

clear, and lexact description.

My invention vrelates to soap dispensers, particularly of that type inwhich a quantity of liquidsoap 'or compound. is'stored in a vessel orreceptacle provided with means for suitably discharging small quantitieswhen desired.4

It is the purpose of my present invention Y. to improve andsimplifyapparatus of this class, and attain the discharge of the soapy liquid inas convenient and positiveV a mannerf as lpossible. use of a submergedcup or cylinder within the soap receptacle from which the 'iiuid is 'Vdischarged upward through a hollowr depressible plunger cooperatingtherewith. I also provide for veryquick and easy assemhling interiorsurface of the engagement 4, as shown.

The plunger is normally impelled toits upper. limit of movement by a spring 20, or 1n so that thenotches or-holes 12 of thel cylinder 10 are uncovered.

I" nowa quantity of the soapy coni pound isdesire it is merely necessary to depress the knob or handle l5, and thecontents of the cup or cylinder l0 will be discharged upward through thehollow pistonI rod 14, and into said knob or handle from which it mayescape through any suitable discharge orifice such as the laterally anddownwardly extending passage 2l. lVhen tie pressure on the knob orhandle is released, the 'plunger rises to its normal position, and a newcharge enters the cup or cylinder l0 which may be likewise expelleduntil the desired quantity of soapy fluid is' obtained. The capacity ofthe cup or cylinder l0 is, however, such that a single depressionof theplunger discharges or eXpels a quantity of the soapy fluid adequate forordinary needs.

lVhat I claim is rl. In a'soap dispenser, a receptacle, a cover having,a depending' circumferential flange fitting over' said receptacle andhaving a central integral guiding sleeve with an interior lug, a cup orcylinder within said receptacle and having notches on its upper edge,and a hollow plunger coperating with said cup and having a verticalrecess of lim` ite-d vertical extent'engaging said lug, wherebythevertical movement of the plunger is limited to a predetermined throw.

2. n a soap dis enser, a receptacle, a cover having a gluing sleeve withan interior lug, a cup or cylinder within said receptacle, and a plungerhaving a cup shaped knob with a vertical groove embossed integrallyinward on one side and communicating with a lateral and a verticalrecess in said knob and adapted to engage over said lug, whereby theplunger is made removable without weakening the structure of said knob.

In witness whereof, I subscribe my signa ture, in the presence ot' twowitnesses.
